Claims

1. An automatic dishwashing detergent composition consisting essentially of by weight:

(a) from about 0.1% to about 4.0% of a C.sub.11-16 secondary soap;
(b) from about 0.5% to about 2% of a C.sub.12-16 amine oxide;
(c) from about 0.1% to about 10% nonionic surfactant which does not foam selected from the group consisting of polyethylene, polypropylene, and polybutylene oxide condensates of alkyl phenols, condensation products of aliphatic alcohols with from about 1 to about 25 moles of ethylene oxide, condensation products of ethylene oxide with a hydrophobic base formed by the condensation of propylene oxide with propylene glycol; and mixtures thereof;
(d) from about 2% to about 30% of detergency builder selected from the groups consisting of phosphates, carboxylates, polycarboxylates and mixtures thereof; and
(e) from about 0.01% to about 4% active protease enzyme, active amylase enzyme and mixtures thereof;

2. The composition of claim 1 wherein the pH is from about 11 to 13.

3. The composition of claim 1 wherein the composition further consists essentially of from about 2% to about 30% sodium carbonate.
